To all whom' 't may cancer/n.:

Be it known that I, CHARLEs F. SrnRY, 'a citizen of the United States, and resident of Chicago, in the county of Cook and VState of Illinois, have invented new and useful Tmprovements in Radiator Cores, of which the following is a specification.

This invention relates to the construction of cores for radiators of the kind employed to form part of the water cooling system of internal combustion engines.

The object of the present invention is to provide a radiator core of simpleand durable construction. Al further objectis the provision of a core which will thoroughly cool the water passing therethrough, such core having ribbon shaped water-channels the flat sides' of which being able to yield to the expansion of the enclosed body of water, should the water accidentally freeze, thereby saving the core from bursting.

To this end I have provided a structure having water channels of av peculiar Shape andvprovided with spacing members shaped to direct air against the sides of the water channel, all as clearly set forth in the following detailed description, and illustrated in thev appended drawmg, of which:

Fig. 1 is a fragmentary front elevation,

artly in section, of a radiator-core having its limits constructed and shaped in accordance with my invention. One of the units is shown partly in section in order to indicate the appearance ofthe wa'ter-channels,

Fig. 2 illustrates a pair of spacing members removed from the structure of Figi 'and shown slightly separated in order more clearly to indicate the various details of construction. One of the members is shownin cross-section substantially through its center,

Fig. 3 is a fragmentary side elevation of on of the spacing members just referred to, an

Fig. 4 is a corresponding side elevation of one of the side plates of a core unit.

The radiator of my invention is of a honey-comb Shape, comprising a plurality of hexagonal cells combined into Vertical units, each of which forms a separate selfsupporting frame 1, '2, etc. `"When these frames are assembled it is to be noted that the adjacent frame sides combine to form water-channels a, 5,'etc. Tn order to provide the water space between the adjacent side plates necessary to provide thin ribbonlike water-channels, it is pointed out that as'sembled side by side and soldered together, come into contact with each other only along the edge's, where the solder flows in and forms a water-tight joint, and that the intermediate. portion remains in spaced relation, formin the semi-hexagonal ribbon shaped passage or the water.

For the purpose of maintaining the units correctly assembled until the time that the solderhardens and ties them together permanently, li have provided. inter-fitting semi-spherical extrusions, or buttons, 7, 7a, uniformly spaced along the' edges of the frame sides, and these buttons greatly facilitate the assembling operation. It is also to be observed that the top or bottom of one frame is narrow and that of the neixt following frame is wide, a condition which is incidental to the hone-comb shape, and necessary in order that t e top and .bottom surfaces of the whole core may and not crenelated et all the frames of the core are exactly a ike, but each alternate frame is turned upside down.

There is an empty space A within each frame, which space must be filled in some manner, or the thin metal ofthe frames will not retain its shape'during the assembling and solderin Operations, besides, without some proper ller, the honey-comb would be incomplete, insubstantial and not of a pleasing ap arance. Tnto this space insert'a pair o thin metal spacing members 9, which members are exact y alike, and provided along their edges with extrusions, or huttons, 9b, 9, for registration with the buttons 71, 7'1l of'the frame-sides, whereby the said members are held'in correct relation to the frames during the soldering operation. Each member is made with uniformly shaped and spaced semi-hexagonal projections along both front edges, and it is noticed that the vapical surfaces 9** of these projections abut the apical surfaces 7a of the encompassing frame. 'Rising from the center portion of the front surface of these members is a corbe made fiat responding series of transverse-rhombic projections 9a, arranged in staggered relation to said edge projections, in. such a manner that the pointed ends 9' of these rhombic projections commence to rise in the spaces 9? beof cel s re uired to fill the space within each frame, an it is' further observed that the rhombic projections combine to form lozenge shaped bodies, each of which bodies takes a central position withinl each large space between two adjacent water-channels. a

Looking merely at the front (or back) of the core,- the true honey-comb Shape only is apparent, but by sighting through the core, row after row of `corrugated bands are observed, which bands are the walls of the water-channels, winding their Way out and in from top to -bottom in uniformly opposed succession. And in the center of each widening is a lozenge-shaped body. But while the apearance of the structure is important,

- t ere is a distinct purpose in mounting `these lozenge or torpedo-shaped bodies between the water-channels, and the purpose is to split the air current rushing through the core, and to throw it against'the sides of the water-Channels. The exact cross-sectional shape of this lozenge-like deflector is not important, so long as it operates to split the passing air, and the shape indicated in the drawing is merely illustrative of this function.

I claim- 1. In a radiator core, Vertical series of semi-hexagonal ribbon shaped water channels, the air-s aces between said Channels alternately wi ening and narrowing from top to bottom, and lozenge shapedair deflecting bodies centrally positioned within each Widening.

2. In atradiator core, Vertical series of semi-hexagonal ribbon shaped water channels in opposed spaced relation, and spacing members between adjacent water-channels, said ,spacing members made with opposed rhombic projections combining to form air deflectors centrally positioned within space enlarements between said water-channels.

3. n a radiator core, Vertical series of semi-hexagonal ribbon shaped water-channels so related that the air space between deflectors centrally located within each space widening of the water-channels.

4. In a radiator core, Vertical series of semi-hexagonal ribbon shaped water-channels so related that the air space between each adjacent pair of water channels alternately widens and contracts, and a spacer-3.l

between each pair of channels, said spacer comprisin a. pair of thin metal strips having semiexagonal edge projections and placed back to back so that the said projections combine to form a series of spaced hexagons the apices of which abut apices of the water-channels, each spacer formed with a series of rhombic projections, said projections combining to form lozengeshaped bodies positioned centrally within the water-channel widenings.

5. A radiator core comprising identical vertically disposed sheet metal frames the sides of which are bent alternately in and out in opposite directions to form'semi-hexagonal outlines, and assembled in alternate reversed relation, a sheet metal spacer within each frame and having hexagonal edgebands abutting the inner faces of said frame sides, said spacer provided with projections forming lozenge-shaped bodies centrally positioned within widenings between the'frame sides, and means for alining the parts in assembling.

6. In a radiator core, Vertical series of semi-hexagonal ribbon shaped Water-channels so related that the air space between each adjacent pair of water-channels alternately widens and contracts, and a spacer between each pair of channels, said spacer having semi-hexagonal edge bands for en- ,gagement with edge bands of the waterchannels and provided with lozenge-shaped deflectors centrally located within, each space widening of the Water-channels, the water Channels and spacers provided with interfitting alining means capable of maintaining the relations between the assembled parts until the core has passed through the soldering process.
